With Windows 8, Microsoft added a new way of signing into your PC i.e signing in with your Microsoft account.
There are several benefits of using a Microsoft(Earlier Windows Live) account to sign in to your windows PC.
All your settings, pinned websites, lock screen etc are automatically synced as soon as you login with your Microsoft account.
But what to do if you have created a local account and now want to switch to a Microsoft account?
Well don’t worry. Just follow the steps mentioned in the video. (I am assuming that you already have a Microsoft account)
